    '' I2CREAD and I2WRITE Commands

    Include "modedefs.bas"
    DEFINE I2C_SLOW 1
    DEFINE SHIFT_PAUSEUS 1000
    SDO VAR PortB.0
    SCLK var PortB.1

    SCLK = 8
    SO con 0
    DPIN var PORTA.0
    CPIN var PORTA.1
    B0 var byte
    B1 var byte
    B2 var byte
    B3 var byte
    n var byte
    portB = 0
    TRISB = 0
    'for n = 0 to 15

    lookup n,[252,96,218,242,102,182,190,224,254,246],b0 ' numbers from 0 to 9

    For B2 = 0 To 15

    I2CWRITE DPIN,CPIN,$A0,b2,[str B0\8]
    Pause 20


    Next B2
    'next n
    loop: For B3 = 0 To 15
    I2CREAD DPIN,CPIN,$A0,B3,[B1]
    pause 1000

    SHiftOUT SDO,SCLK,0,[b1]
    '

    Next B3



    Goto loop
    end
